Well I keep on depleting the account. I went into my gun shop and found a 27-2 3 1/2 nickel for $350.00. It about 98% but dirty. The finisk looks great. Anyway I'm going to have to put some grips on it. I need reccomendations. What would be the smallest N frame squares available? Also, I know folks seem to like the 3 1/2 but are they actually rarer than the other lengths?
